This invention relates to novel molecular complexes. More specifically, the present invention relates to novel and useful molecular complexes comprising a bis-(5- nitrofurfurylidene)-acetoneguanylhydrazone and acid addition salts thereof and an amine and to feed additive premixes and feed compositions containing them.

The novel molecular complexes of the present invention are utilized as animal feed additives and as such are highly desirable. Numerous additives have been utilized in animal feed compositions in an attempt to accelerate the growth of young domestic animals, e.g. cattle, swine, sheep, chickens, turkeys, ducklings and the like. A rapid growth rate in domestic animals is of great economic importance because the more rapid the growth the greater the proportion of feed which is transformed into meat. Animal feed additives are also utilized to afford protection against certain infectious diseases. The molecular complexes of the present invention exhibit a surprisingly high activity when utilized to promote growth and anti-infection properties in animal feed compositions.

Bis-( 5-nitrofurfurylidene )-acetoneguan ylhydrazone and its addition salts have been utilized as animal feed additives as disclosed in US. Pat. No. 3,264,112. Applicant is, however, unaware of any prior art which discloses the molecular complexes of the present invention of their surprisingly high activity in promoting growth and anti-infection properties.

It is, therefore, an object of the present invention to provide novel animal feed additives.

It is a further object to provide molecular complexes of a bis-( 5-nitrofurfurylidene)-acetoneguanylhydrazone and acid addition salts thereof and an amine.

These and other objects of the present invention will be readily apparent to one skilled in the art upon the reading of the description of the invention which follows.

These objects are achieved by reacting a bis-(5- nitrofurfuryliden )-acetoneguanylhydrazone compound of the formula wherein R is hydrogen, lower alkyl or halogen, R is hydrogen or lower alkyl and X is a mono-. di-. or tribasic acid. H is 1,2, or 3 with the proviso that when X is monobasic u is 1, when X is dibasic n is l or Z. and when X is tribasic n is l, 2 or 3; with a suitable amine to form the desired molecular complex. A preferred bis-( S-nit rofu rfurylidene )-acetoneguanylhydrazone acid addition salt is the hydrochloride commercially available under the name Nitrovin" from the American Cyanamid Company. A preferred bis-(S-nitrofurfurylidene-acetoneguanylhydrazone is the compound in which R and R are both hydrogen.

Suitable amines which can be utilized include primary, secondary and tertiary amines and these may be aliphatic, aromatic or heterocyclic. They may be mono-. di-, trior polyamines. Specific amines which can be utilized in the present invention include phenylene diamine', piperazine'. hydroxyethyl piperazine: N- alkyl piperazines, e.g.. Nmethyl, N-ethyl. N-propyl. N butyl, N-cetyl and N-lauryl; N-(aryl substituted) alkyl piperazines, e.g. N-benzyl piperazine; guanidine; aminoethyl piperazine; p-aminobenzoic acid; nicotinic acid; picolinic acid; nicotinic acid amide; pyrrolidine; triethylamine; methyl aniline. Z-hydroxy. Z-hydroxy- 4,6-dimethylpyrimidine1 n-hexylamine'. a-picoline; pyrrole; amino-cyclohexane; glycine; lysine: and the like. A preferred amine is 2-hydroxy-4.6-dimethylpyrimidine.

A preferred method of preparing the molecular complexes of the present invention comprises dissolving the amine in a suitable solvent. e.g.. methanol. and then adding the bis-( S-nitrofurfurylidene )-acetoneguanylhydrazone or an acid addition salt thereof. The resulting mixture is stirred at room temperature for about sixteen hours and the resulting product is then filtered. e.g. by suction, washed and dried to yield the desired molecular complex.

The molecular complex compounds of this invention may be utilized alone or in admixture with suitable carriers. They may be utilized with either acid or alkaline carriers because of their extreme stability. Numerous carriers are available and one is normally selected on the basis of cost, inertness to the molecular complex and tolerance by the particular animal. The following list contains but a few of the nutritive materials which have been or may be employed as carriers: corn meal. corn cob meal, milo, soybean oil meal, alfalfa meal. dried whey, wheat shorts, distillers dried solubles, salt. meat scraps, calcite, feather meal, poultry by-products wheat middlings, dextrose, lactose meal, dried kelp. linseed oil meal, oatmeal, dried yeast, wheat bran, soybean meal and the like.

The compounds of this invention may be provided as premixes or as concentrated mixtures which may then be used to prepare the complete feed mixture. The premix is usually prepared to contain 4 grams of the molecular complex per pound, however. multiple strength premixes, e.g., those containing 8, l2, 16, 24, 32 and 64 grams of the molecular complex per pound, can also be prepared and utilized. The premix can then be combined with other ingredients to form a complete feed, e.g., about one-quarter pound of premix with about one ton of other ingredients will form a complete chicken feed. Complete feed for other animals can be similarly formulated. A complete feed composition can also be directly prepared containing from about 1 gram to 3 about grams of the desired molecular complex per ton of composition without utilizing the premix composition.

The following examples will illustrate in detail the manner in which the invention may be practiced. It will be understood, however. that the invention is not confined to the specific limitations set forth in the examples. but rather to the scope of the appended claims.

EXAMPLE I L98 g. (0.0l6 mole) of Z-hydroxy-4.6-dimethylpyrimidine were dissolved in 10 ml. of methanol and with continuous stirring 3.97 g. (0.0l mole) ofNitrovin were slowly added in small portions. The resulting mixture was stirred at room temperature for a period of 16 hours and then filtered by suction on a glass-sintered filter. The filtered product was then washed with a small amount of methanol and dried at about C. yielding 4.85 g. of an orange-brown powder. Analysis of the product confirmed the structure to be the desired molecular complex.
